6 Claims.

The present invention pertains to fly shuttle looms, and more particularly relates to shuttle boxes for such looms.

Looms of the type mentioned commonly include a reciprocating lay on which is mounted a reed and a shuttle box. The shuttle box includes a back box plate having a shuttle guiding surface which must be accurately aligned with the reed in order that the shuttle may be properly picked into and out of the shuttle box.

Various constructions have been proposed for aligning the shuttle guiding surface with the reed. However, these constructions have either been too complicated and difiicult to adjust or have not given the accuracy of alignment required.

Accordingly, it is a principal object of the present invention to provide in a loom having a lay on which is mounted a reed and a shuttle guiding member, a supporting member for the lay and means adjustably connecting the shuttle guiding member to the supporting member, said means comprising a plate positioned between the supporting member and the shuttle guiding member, threaded means adjustably connecting the plate to one of said members, for moving the shuttle guiding member transversely of the lay and tilting same about ahorizontal axis extending longitudinally of the lay, and means for locking said shuttle guiding member to said supporting member in adjusted position.

The foregoing and other objects of the invention are accomplished in the construction illustrated on the accompanying drawing, of which:

Fig. 1 is a plan view of a lay beam, shuttle box and other parts of a loom to which the invention has been applied.

Fig. 2 is a horizontal section of certain parts of Fig. 1, this view being to a larger scale.

Fig. 3 is a front view of a portion of the lay beam and the inner end of the shuttle box, and

Fig. 4 is a section View taken on line 4-4 of Fig. 2, this view being to a larger scale.

The drawing shows but part of a 100m having my invention applied thereto, the parts and mechanisms not shown being of any suitable usual construction and forming no part of the present invention. The drawing shows a portion of the right hand end of the usual lay beam I which is fixed. to the front face of a sword 2. The lay beam carries a reed 3 and a shuttle box indicated generally at 4. The shuttle box includes a front box plate 5 and a back box plate the outer end 6 of which is fixedto the lay beam as by means of bolt 1. The back box plate is provided with a shuttle guiding surface which must be accurately aligned with the reed as is well known in the art. I

The particular back box plate shown is constructed of two separate members, the outer end or member 6 and the inner end or member 8, which carries the shuttle guiding surface 9. The two members may be connected together by a universal joint indicated generally at I0 and more fully disclosed in patent to W. I. Stimpson No. 1,848,674 granted March 8, 1932.

The universal joint permits the inner end or shuttle guiding member 8 to be adjusted about difierent axes, one extending horizontally longitudinally of the lay and shuttle box and the other extending vertically. Thus the shuttle guiding member 8, carrying the shuttle guiding surface 9, may be tilted about a horizontal axis to bring the shuttle guiding surface into a plane parallel with the reed and may be moved bodily forwardly or rearwardly transversely of the lay beam to bring the shuttle guiding surface into horizontal alignment with the reed.

The inner end or member 8 of the back box plate is attached to the sword 2' by means which can be manipulated to produce the desired adjustment of the shuttle guiding surface, the member being firmly fixed in position after the adjustment is accomplished.

Such adjusting means may comprise a wedge shaped member II positioned between the sword 2 and the members of the back box plate. Member II may be adjustably connected to member 8 by a plurality of adjusting screws, in the drawing three such screws I2, I3 and M are shown. Each of screws I2, I3 and I4 is left hand threaded on the end that screws into member I I and right hand threaded on the end that screws into member 8. The ends of the screws in member 8 are slotted to facilitate adjustment. Screw I2 is located above, screw I3 is located below and screw I4 is located substantially on the longitudinal center line of member 8. Thus by adjusting screws I2, I3 and M the box plate member 8 may be bodily moved toward and from member I I and may be tilted about a horizontal axis extending longitudinally of the lay.

The wedge shaped member II has an opening I5 therein for the reception of a boss I6 formed on the box plate member 8. The wedge shaped member Il may have fitting strips which bear against the sword, three such strips II, I8 and I9 are shown on the drawing.

Fastening means are provided for fastening the members 8 and II to the sword 2. Such fastening means may comprise a threaded member or cap screw 2!]. Cap screw 20 extends through a vertically elongated opening 2| in the sword 2, through the opening I in member H and is threaded into the boss I G on member 8. By means of cap screw 20 the members 8 and l I may be moved bodily transversely of the lay beam towards and from the sword 2.

The operation of the device is as follows:

To turn the member 8 about a horizontal axis to bring the shuttle guiding surface 9 into a plane parallel with the reed, the cap screw 20 is loosened and by properly adjusting screws l2, l3 and I 4 member 8 i angularly adjusted relative to member ll so that when the assembly is clamped against the sword 2 by tightening the cap screw 20 the shuttle guiding surface 9 is in a plane parallel with the reed. To move the shuttle guiding surface bodily to bring the shuttle guiding surface into horizontal alignment with the reed, the cap screw 20 and screws l2, l3 and I4 are adjusted to give the member 8 the required movement.

Having thus fully disclosed the preferred embodiment of my invention; I claim:

1. In a loom, a lay including a reed and a shuttle box having a shuttle guiding member adapted to be aligned with the reed, a sword for supporting said lay and to which said shuttle guiding member is adjustably attached, a plate positioned between said sword and said shuttle guiding member, threaded means adjustably connecting said shuttle guiding member to said plate, said means being so constructed and arranged as to provide bodily movement of said shuttle guiding member toward and from said plate and tilting movement of said shuttle guiding member about a horizontal axis extending longitudinally of the lay and means for locking said shuttle guiding member in adjusted position.

2. In a loom, a lay having a reed along which a shuttle may run, a shuttle guiding member independent of the reed supported by said lay, a member for supporting said lay and to which said shuttle guiding member is adjustably attached, a plate positioned between said members, threaded means adjustably connecting said plate to one of said members, said means being so constructed and arranged as to provide bodily movement of said shuttle guiding member towards and from said supporting member and a tilting movement of said shuttle guiding member about a horizontal axis extending longitudinally of the lay and means for locking said plat and said members together.
